These small galaxies are somewhat hard to detect in or near the plane of the Milky Way (thus, the uncertainty about the number); one such galaxy is the Ursa Minor Dwarf Galaxy. It was discovered ...

We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs ... spectroscopic survey of the Ursa Minor (UMi) dSph. We identify 892 likely ...

This Hubble image reveals why it’s an apt moniker: The galaxy boasts nine rings, six more than any other known. The rings formed like ripples in a pond after a blue dwarf galaxy ripped through ...

However, existing galaxy formation models under the ΛCDM paradigm fail to explain the formation of diffuse dwarf galaxies in old halos, implying potential contradictions between current galaxy ...

It may come down to a coin toss as to whether the Milky Way collides with the Andromeda Galaxy within 10 billion ... “It’s not just a minor satellite, but it’s a major player.” ...

Every major galaxy like the Milky Way has a retinue of smaller dwarf galaxies orbiting it. The Milky Way has several dozen, including the famous Large and Small Magellanic clouds. Beginning in the ...

The James Webb Space Telescope (JWST) has captured a breathtaking new deep field image of the galaxy cluster Abell S1063, surpassing Hubble’s previous view in both depth and detail. Abell S1063 ...

Like magnificent large spiral galaxies, small galaxies also form stars. In the image, the dwarf irregular galaxy "Ugc 2858" shows bright blue young star clusters and pink areas where stars are ...

The current North Star can be found easily by locating the Big Dipper asterism in Ursa Minor, which is high overhead this time of year. Draw an imaginary line from the magnitude 2.3 star Merak ...

But so far, there have been only faint, sketchy hints of IMBHs residing in dwarf galaxies, and no direct evidence that they live in a galaxy like the Milky Way. In April, a team of researchers at ...

the Milky Way becomes more likely to cannibalize this satellite dwarf galaxy. According to this research, our galaxy is almost certain to merge with the Large Magellanic Cloud over the next 2 ...
